Launching Frequency Requirement
Launching Frequency Requirement
(OP)
Hi I am reading the article below and found that the launching requirement for satellite frequency is MUST BE LESS THAN ...
I am curious why less than? Isn't it we should design it more than the fundamental frequency?
"The fundamental frequency of the satellite must be less
than 100 Hz in the longitudinal direction and less than
50 Hz in the lateral direction."

RE: Launching Frequency Requirement
Not necessarily; our specs for a non-space payload was that component resonances were of concern only if they constituted more than 10% of the total payload weight. That should be pretty intuitive; something tiny with a bad resonant frequency wouldn't necessarily be capable of affecting the entire payload.

Thanks IRstuff, I would agree that taking 10% of the total payload to pick those critical components...
